I teach 4 classes at community colleges in the Inland Empire. Math. Idk to give daily presentations you have to be somewhat aggressive/assertive tbh which leads to liking metal. Or is it the other way around? We listen to metal to keep us pumped to be aggressive/assertive? It takes a certain level of balls to get up there and talk to different groups of 30+ people for 4 hours a day.
I don't teach people at a school, but I do sometimes give presentations as part of my job with the goal to deliver information and sometimes, in rare instances, training. It can be for one person or a few hundred, depending.
Today I passed around a "Sine in sheet" in my Trig class. It was fun seeing which ones laughed and which ones didn't get it as it was passed around 1 by 1.
